Fig. 5 is a siinilar cross-section, t-.ilien on the line 5--5 oli Fig. 1.

Fig. is a perspective view ol' the block; and.

i" is a. bottoni perspective view of the shiitable riding section.

Il have exeiiiplilied iny invention as applied to a railway track construction einbodying a niain track en'iploying rails 11, 12 and 13, and a diagonal crossing track, which inay be teriiied a sidetrack, eiiibodying rails 14 and 15 and a coinpleineiital track not shown. il block 17 has thereon a lixed lrog point 18, at the sides nl ivliieh there are ilangeways 19, 20, merging into a throat 2X1 and a inout-h in advance et the li'og point. The bloei; has a heel extension E23, iorn'iing recesses Q4, 25, at the sides of the rear end ot the block. v i

The bloel; is provided with riding siirfaees 31, 32, at one side of the lrog point, which are spaced apart lengthwise ol the liangeways by a space 33. il. sliiiltable rid* ing section is located in said space, and

'is shown pivoted to the blocli oii a pivot lug 36, received in a pivot hole 37 in said block, and held to said bloclr by a securing pin 38. This space has a bottoni wall and merges into the l'laiigeways in the block. The bottoni wall forms a supporting snrn iiace for the sliilftalile riding section` on which the swinging end of the sliiitable rid ing section is nioved laterally toward and trein the frog point.

The iiiovenient oi the shittable riding section is obtained in suitable manner, and may be automatic lor normally moving the Shiitalole riding section into eoaetive relation with the frog point and locating the shittable riding section in the laiigeway at` the side of the ilrog point :tor continuity oi riding siii/'tace along the inain traelr. lll? desired, the sliiltable riding section niay have connection with a; inaniial lever oi' with a tower controlling lever for locating 'the shiftable riding section in desired position.

The rails 11 and 14 are shown converging toward the frog point. They are provided with spread portions, shown generally at 41, 42, between which the block is received and secured. These spread portions n'iay include outwardly diverging port-ions 43, 44, prefierably bent integrally lroin the converging inain portions el the rails, which spreading portions merge into convergingportions 45, 46, which in tiirn inerge into diverging portions 47, 48, respectively substantially parallel with the rails 15 and 12. The bloeit is exemplified as comprising side walls 51, forming tongues, received in the inner .side channels in the bulging portions el the rails 11, 14, the lower ends olf these side walls being supported by the bases of said rails.

A separatinga block 53 is received between the converging end portions oi the rails 11, 14, being received in the inner side channels oi said rails.

The heel extension of the block is provided witli tongues 54, respectively received ill) in the side channels of the rails 12, 15. Blocks are received between the ends of said rails and the lapping ends of the reinforce rails or bars for the frog block, these separating blocks being provided with tongues received in theside channels of said rails. f

Bolts 56 are received through said frog block and said reinforcing rails or bars for rigidlyseeuring the same together, similar bolts being received through the rails 11 and 14 and the separating bloclr 53, and through the lapping portions of 'the reinforce rails Vor bars and thel rails 12, 15, the separating blocks 55, and the heel extension 23 of the frog block 17. Suitable nuts 5T and lock washers y58 are yreceived over the bolts for clamping the parts ,rigidly together.

In the present exempliiication, the bulged portions 41, 42, which form the reinforce rails, are integral with the rails 11, 14, and encompass the frog block, and the 'rear ends of said reinforce rails overlap the rails 12, 15, in rear of the frog block, and the heel ei:- tension of the frog block, said lapping portions of said rails and said he'el extension be- :inI

ing secured'tegether, whereby creeping of the, frog block and of said rails is definitely prevented. The frog bleek is preferably provided with a web 61 which extends between `the .side Walls of the frog block. The riding surfaces of the frog block are preferably located on said web. f

The rear end of the heel extension may be provided with an easer surface 62, which is arranged tobe contacted by the so-called false flange at the outer end of the tread of the wheel, so as to ease the wheel on to the rails and the riding surfaces of the frog. In practice the wheel 64 usually7 becomes Vworn adjacent 4to its iange 65, the riding periphery of the wheel adjacent to its flange having an annular groove 66 formed therein by pressure and wear, and leaving ,theouter end 67 of the tread of the wheel of greater diameter than the diameter' of saidv wheel at said groove, and forming the so-called false flange. This is exemplified in dotted lines in, Fig. 4.

-The heel ends of the bulge of the reinforce rails are also preferably provided with caser faces 69, which slant downwardly and forwardly for forming mouths at the heel end of the frog block, to insure ready entrance ofthe flanges of the traveling wheels into the langeways in the frog block.

`An easercrail V71 having an easer face 72 may be located at the outer face of the rail 11, so as to 'ease the false anges on the Wheels traveling over the main track upon the diverging portion of said'rail and the ridinfr surfaces on the frog block, and to ease thew eels off said rail and riding surfaces. This easer rail may be secured to the rails and blocks at the side thereof by the :tasten ing means securing said rails and blocks to gether, suitable iiller blocks being located in the proximate side channels et said rails 11 and 71. ',lhis additional caser rail, howerer, is not essential, because the il.iverginj.;` portions 43, 44, of the rails l1, lll, are presented slantingly toward the t: :fe iiangiges nl' the wheels passing thereorey, so as to ease the wheels with relation to the frog block and the rails, which easing is eniphasr/:ed b v the rounded edges of the heads of' said divergirgl portions of said rails. l

rlhe shit'table riding section Sii niay be normally urged toward the frog point, :is by means of springs between the reinforce rail at the side of the frog lilocl and :i lng 'T6 extending downuuirdlv from the shi'lftable riding section through a [17 in the upper wall of the frog block. fr bolt In is received through the reinforce rails, through a hole TS) in a depending lng 8O of the block and hole 81 in the depending lng 76, the spring being received between the last-named lug` and a flange bushing 82 in a hole in the reinforce rail ell, a nut S3 being received over :l reduced threaded end of said bolt and suitably secured in place for maintaining the parts in connected relation. Y

if desired, 'the shiftablc riding .acct ion may be manuaily operated, as by means oil a rod 85 received tlnough a lug S6 ezioiiiliiig 'roin the lug '(6.

Slot

The head Si? of the rodliinilsI inward movement ofthe shiitable riding sec tion. The roc 535 may have articulation SS with a suitable bell cranllever till, pivoted on a fixed pirot to the road bed, and operated by a rod 9i articulate"L with said hell crank lev r at 92. The rod Sil may he operated in suitable manner, as by nicans of an ordinary weighted manually operated lever at the side of the track, or the rod 91 muy lead to a suitable tower control lor operating the shiftable riding section. Y

The reinforce rail l1 may be provided with a recess 95, the bottom et which ruis a support for tic shiftable riding` section. ',lhe shiftable riding section is foi-ined with an Lipper wall 96, which Vloinis a corer for the space 97 netvv'een the inner llanggje in; ol the shiftable riding section and the reinforce rail portion 41, this cover being also received over the spring and its connections l'or protecting the saine and said space from dirt. snow and injury.

The end 101 ofthe shiiahle riding` section and the end walls 10Q ot the recesses -l'l :ind 97 may be formed ou an arc described from the pivotal anis of the pivoted riding .section as a center, for inevcntinej wcdnjing action between said faces and insuring Vtreedoni ol movement of the riding section.

A tread guard 105 may be provided at the side of the rail frog opposite to the shi ltable riding section. It is shown as part ol Sli lill) lil lib

till

the block i7 and is arranged to be `engaged by the outer end of the tread of the Wheel passing over the rails, for shifting the flange of the rail inwardly so that when the wheel passes the frog point, the flange of the wheel will be spaced. inwardly from said frog point for preventing contact with the frog point and thereby preventing injury to the frog point. This construction also insures positive movement of the shiftable riding section, which is moved by the flange end of the wheel. This tread guard may be provided with easer faces 10G at the respective ends thereof.

The shiftable riding section is atits swinging end provided with a receding inner wall lill' arranged to be engaged by the flange traveling in the flangeway 2O toward the front of the frog along the siding, for shifting the shiftable riding section laterally away from the frog, so that said flange may readily pass through the throat and the mouth of the frog. Then the railway vehicle moving in the opposite direction along the siding, the flange of the wheel strikes the wall 108 of the shiftable riding section which normally fills the gap between the riding surfaces at the frog in the main track, for readily shifting said shiftable riding section to permit passage of the vehicle along the siding track. The springs 75 normally retract the shiftable riding section toward the frog point.

rllhe frog block is preferably of wear resisting metal, for instance a manganese steel casting.

The connection between the lug 86 and the rod 555 is preferably a loose connection so that when the shiftable riding section is adjacent to the frog point it may readily be moved by the wheel against the resistance of the spring, in which relation the lug 8G moves along the rod 85. This places the automatic yielding of the shiftable riding section independent of the manual control thereof.
